Final answer:
A sample statistic related to political affiliation in a state might be the percentage of registered Republicans or Democrats in a selected sample supposed to represent the state's population.
Step-by-step explanation:
If political affiliation is considered a population parameter in a specific U.S. state, an example of a sample statistic for this population could be the percentage of registered democrats, republicans, or independents in a randomly selected group of voters from that state. For example, if we have data stating that 58 percent of registered voters in a community are registered as republicans, and we want to conduct a study to verify if this percentage holds up in a different part of the community, we might collect a sample and find that in this sample 53 percent are registered republicans. This 53 percent would be the sample statistic which is an estimate of the actual population parameter.
The difference between a population parameter and a sample statistic is that a parameter refers to the entire population, while a statistic is an estimate based on a sample from that population.If an insurance company is interested in the proportion of all medical doctors involved in malpractice lawsuits (the population parameter), they might take a sample of 500 doctors and determine the proportion within this sample that have been involved in such lawsuits (the sample statistic).
